Abstract
In a method and apparatus for producing a small pouch with a predetermined amount of particulate material therein, a predetermined amount of the particulate material is portioned from a bulk supply and compacted into a single discrete caplet. The caplet is then deposited into an open hollow pouch closed at one end thereof, and the open end is then closed with the caplet between the closed ends of the pouch. The caplet in the pouch is then compressed to return it to its particulate form. The particulate material may be granular or shredded tobacco.
Claims19
An apparatus for forming an oral pouch product, the apparatus comprising:
- a caplet forming device configured to form a caplet from a particulate material;
- a feeding device configured to receive the caplet from the caplet forming device and direct the caplet into a flexible web;
- a first sealing device configured to close the flexible web around the caplet so as to form a pouch having the caplet therein;
- and
- a compression device configured to engage the caplet so as to return the caplet to a particulate material,
- wherein the compression device includes a pair of compression rollers.
An apparatus for forming an oral pouch product, the apparatus comprising:
- a caplet forming device configured to form a caplet from a particulate material;
- a feeding device configured to receive the caplet from the caplet forming device and direct the caplet into a flexible web;
- a first sealing device configured to close the flexible web around the caplet so as to form a pouch having the caplet therein;
- a compression device configured to engage the caplet so as to return the caplet to a particulate material;
- and
- a clamp configured to engage the flexible web, wherein the clamp is configured to engage the flexible web during compression of the caplet.
An apparatus for forming an oral pouch product, the apparatus comprising:
- a hopper configured to hold a supply of a particulate material;
- a supply of a flexible web;
- a caplet forming device configured to form a caplet from the particulate material;
- a first sealing device configured to create a longitudinal seal on the flexible web so as to form a tube of the flexible web;
- a feeding device configured to receive the caplet from the caplet forming device and direct the caplet into the tube of the flexible web;
- a drive roller configured to translate the tube of the flexible web;
- a second sealing device configured to close the flexible web around the caplet so as to form a pouch having the caplet therein;
- a cutting device configured to separate a portion of the flexible web from a remainder of the flexible web;
- a clamp configured to engage the flexible web;
- and
- a compression device configured to compress the caplet so as to return the caplet to a particulate material,
- wherein the clamp is configured to engage the flexible web during compression of the caplet.
